Glass Tempering Machine heating time for glass with holes and grooves should be increased by 2.5% - 5% compared to the ordinary glass of the same specification;

The heating time for glass with a sharp corner less than 30° should be reduced by 2.5% - 5% compared with ordinary glass. This type of glass should be loaded in the way that the sharp corner will enter last. Place some waste glass around the sharp corner to prevent it from warping caused by absorbing heat too quickly; The heating time for patterned glass shall be determined according to the thickest part of the glass;

Compared with ordinary glass, the heating time for regular heat-reflective coated glass and tinted glass shall decrease by an appropriate amount depending on the thickness and size of the glass sheet, usually 3 - 5%;

The tempering heating time for Low-E glass should increase by an appropriate amount compared with that for an ordinary glass of the same thickness, and S02 gas is not allowed; glass should be loaded with the coated side facing up to protect the Low-E coating.
